PURPOSE To report the clinicopathological findings of a Chinese patient with an unusual phenotype of gelatinous drop-like corneal dystrophy (GDLD) combined with spheroidal degeneration and to detect molecular defect in the tumor-associated calcium signal transducer 2 (TACSTD2) gene. METHODS Extensive physical and ophthalmologic examination of the patient was performed. Initially superficial k...

The temperatures of prolate and oblate spheroidal dust grains in the envelopes of stars of various spectral types are calculated. Homogeneous particles with aspect ratios a/b ≤ 10 composed of amorphous carbon, iron, dirty ice, various silicates, and other materials are considered. The temperatures of spherical and spheroidal particles were found to vary similarly with particle size, distance to...

Enhancement in backscattering known as glory scattering results from geometric and material properties of spherically symmetric scatterers. The wave-front shape near the spherical scatterer is locally a circular torus. Radiation from a toroidal wave front is axially focused on the backward-directed axis. It is shown that the axial point caustic unfolds to an astroid caustic as the scatterer's s...

The discrete prolate spheroidal sequences (DPSSs) are a set of orthonormal in ℓ2(Z) which strictly bandlimited to frequency band [−W,W] and maximally concentrated time interval {0,…,N−1}. timelimited DPSSs (sometimes referred as the Slepian basis) an vectors CN whose Fourier transform (DTFT) is [−W,W]. Due these properties, have wide variety signal processing applications. eigensequences timeli...
